SR — ADC clock frequency (depends on
ADC configuration)
(The duty cycle depends on ADC
clock2 frequency)
2 AD_clk clock is always half of the ADC module input clock defined via the auxiliary clock divider for the ADC.

3 When configured to allow 60 MHz ADC, the minimum ADC clock speed is 9 MHz, below which the precision is lost.

ts
— D Sampling time4
4 During the sampling time the input capacitance CS can be charged/discharged by the external source. The internal
resistance of the analog source must allow the capacitance to reach its final voltage level within ts. After the end of
the sampling time ts, changes of the analog input voltage have no effect on the conversion result. Values for the
sample clock ts depend on programming.
